A dielectric of dielectric constant 3 fills three fourth of the space between plates of a parallel plate capacitor. What percentage of the energy is stored n the dielectric? My attempt to solve this is given in attachment. The answer is given as 50%. I don't know how to arrive that. Please help revered members
C1 is the free space capacitance C2 is the filled space capacitance C1 & C2 are effectively in series Where A is the plate area and d is the total plate separation distance. So C1=C2 Being equal and in series they will each have half of the total voltage applied to the capacitance. Having equal voltage & equal capacitance means they have equal energy - so they share half the total energy stored on their combined equivalent series capacitance.
